|Corrugated Polycarbonate for Horticultural Applications|
In general, polycarbonate is inherently susceptible to condensate formation, especially when used to cover totally enclosed environments like greenhouses. DYNAGLAS Plus is made with an exclusive manufacturing process that results in the industry's first and most extensive 10-year condensate control warranty. Because effective condensate control is such a critical need for greenhouse growers, the "Plus" condensate control feature is now built-in to every DYNAGLAS product.
Side Lap Fastening Solutions
Palram now offers new closure solutions for DYNAGLAS Plus. The Side Lap Profile and the Lap Clip help maintain an air-tight seal between the DYNAGLAS Plus corrugated sheets, providing more efficient environmental control. The new closure solution is designed to prevent energy loss, damage by strong winds, and internal infiltration of dust, insects and water.

Do I really need to buy Palram's recommended closure strips and screws?
In order to ensure long-term warranty coverage, it is highly recommended to use Palram-approved fasteners and accessories. Palram corrugated products, fasteners and accessories should be thought of as a system meant to provide the best possible installation. Proper use of the complete system (panels, closure strips, fasteners, etc.) greatly reduces the possibility of problems and insures that product warranty will be honored. Please see the installation instructions for the specific product for details.
Why can't I just nail the panels into place?
There are a couple of problems with nailing Palram panels. First, there is significant possibility for impact damage to the panel in the area of the attachment. Second, nailing the panels in place prevents them from safely expanding and contracting with temperature change, resulting in warping of the product. Please be sure to read the installation instructions available on each product's document page on this website.
Why do I have to predrill fastener holes?
Predrilling the holes insures the panels will have room to expand and contract properly with temperature change. Skipping this step can lead to distorted or warped panels. Please be sure to read the installation instructions located on the specific product's document page.
How do I cut these panels?
Corrugated and Multi-wall panels may be cut with a circular saw (using a very fine-toothed blade for plastic panels, veneer, or plywood). For best results, it is often better to cut a few corrugated panels at a time to reduce vibration; clamping the panels also helps. Also, if using a standard circular saw blade, better results may be seen by running the blade backwards (turn it over to reverse direction). Panels may also be cut by hand by carefully using tin snips or a utility knife. For other cutting instructions and further details, please visit each product's document page.

corrugated polycarbonate panels. Our Sunlite
multi-wall panels are available in select markets as well. Suntuf is widely available at Home Depot's throughout North America, as well as many indepent retailers. Sunlite is available at select Home Depot's and some independent retailers.
For commercial applications, our DynaGlas
panels are a great choice. DynaGlas and ThermaGlas are available from Commercial Greenhouse Manufacturers and Greenhouse Supply Distributors. Contact our Master Distributor, Green-Tek
, for a Dealer near you.
Feel free to contact us
with your specific needs and we'll help you make the best decision for your application.
Do Palram products keep the "heat" out?
Palram products are available in a variety of colors (varies by product), each with its own heat and light transmission properties. While all Palram panels block virtually 100% of harmful UV radiation, there are variations in heat and light transmission.
Clear panels allow most solar light and heat through while lighter, opaque colors are more reflective. If excessive heat buildup is a concern, our "Solar Control" panels are you're best bet. Please see each product page for more information on color offerings, light transmission percentages and warranty terms.
How long do the panels last?
Palram manufactures a variety of different products for different applications. Most have industry-leading warranties against manufacture-related defects, as well as specific warranties related to the intended use for the product. However, with proper installation and maintenance, we expect our products to far exceed the warranty periods.
Many of our products are engineered to be installed outdoors and are warranted accordingly. Nevertheless, the lifespan of outdoor products can be affected by how well they were installed, as well as environmental factors like air pollution, winds, and erosion by sand particles.
Warranty details can be found in the Downloads tab under the Warranties section at the bottom of the page for each individual product.
Is there a paint that is appropriate for polycarbonate?
Unfortunately we can’t recommend painting our panels. While polycarbonate is a very resilient material, it is potentially sensitive to chemicals contained in many exterior paints. While we can test a paint for compatibility, we have no way of controlling whether a paint manufacturer will remain consistent with their formulas over time.
My building inspector says I need to know your flame spread rating. Can you provide this information?
Yes. We can provide test reports and other such documents. Please contact your Palram Dealer if you require these data, or Contact Us
. This is technical data and is not to be considered a warranty.
In roofing with corrugated panels, where should I start?
You can choose to install left to right, or right to left, or start at the middle and continue to both sides. It is recommended to always advance against the dominant wind at the site. Never start at both sides, or at any two separate points.
In roofing with corrugated panels, should I insert screws at the corrugation valley or crest points?
Crest fastening is always be preferred, but some corrugated product require fastening in the corrugation valley. See the individual Installation Guide for each product to see specific instructions.
Is it OK to screw in fasteners using a power screwdriver or screw gun?
Adjustable electric screwdriver is allowed, provided you set the torque to the minimal needed, in order to prevent over-tightening and local deformation of the panel. For that reason, pneumatic tools should be avoided.
Is it OK to walk over roofing sheets while in storage, during or after installation?
No. In case it can’t be avoided during installation. It's recommended to use a crawl board that is strong enough to support the weight of the person, and that spans at least three purlins or supporting members.
